Chloroform industrial grade chloroform e nang le bohloeki bo phahameng
Thepa
Seela se se nang mmala le se bonaletsang. E na le refraction e matla. E na le monko o khethehileng. E latsoeha monate. Ha e che habonolo. Ha e pepesehetse khanya ea letsatsi kapa e na le oxidized moeeng, butle-butle e senyeha ebe e hlahisa phosgene (carbyl chloride). Ka hona, 1% ea ethanol hangata e eketsoa e le stabilizer. E ka kopanngoa le ethanol, ether, benzene, petroleum ether, carbon tetrachloride, carbon disulfide le oli. ImL e qhibiliha ka metsing a ka bang 200mL (25 ℃). Ka kakaretso e ke ke ea chesa, empa nako e telele ho pepesehela lelakabe le bulehileng le mocheso o phahameng o ntse o ka chesa. Ka metsi a feteletseng, khanya, mocheso o phahameng o tla etsahala ho bola, ho thehoa ha phosgene e chefo haholo le e senyang le hydrogen chloride. Metheo e matla joalo ka lye le potassium hydroxide e ka senya chloroform hore e be li-chlorate le lifomate. Ketsong ea alkali e matla le metsi, e ka etsa liqhomane. Mocheso o phahameng oa ho kopana le metsi, ho senya, ho senyeha ha tšepe le litšepe tse ling, ho bola ha polasetiki le rabara.
Tshebetso
Trichloromethane ea indasteri e ile ea hlatsuoa ka metsi ho tlosa ethanol, aldehyde le hydrogen chloride, ebe e hlatsuoa ka concentrated sulfuric acid le sodium hydroxide solution ka ho latellana. Metsi a ile a lekoa hore a na le alkaline 'me a hlatsuoa habeli. Kamora ho omisa ka anhydrous calcium chloride, distillation, ho fumana trichloromethane e hloekileng.
Polokelo
Chloroform ke k'hemik'hale ea tlhaho e atisang ho sebelisoa e le solvent le reaction medium. Ha e fetohe, e ka cha ebile ea phatloha. Ka hona, ela hloko lintlha tse latelang ha u e boloka:
1. Tikoloho ea polokelo: Chloroform e lokela ho bolokoa sebakeng se pholileng, se omeletseng le se nang le moea o motle, hole le letsatsi le mocheso o phahameng. Sebaka sa polokelo se lokela ho ba hole le mollo, mocheso le oxidant, lisebelisoa tse thibelang ho phatloha.
2. Sephutheloana: Chloroform e lokela ho bolokoa ka har’a nkho e sa keneng moea ea boleng bo tsitsitseng, joalo ka libotlolo tsa khalase, libotlolo tsa polasetiki kapa meqomo ea tšepe. Botšepehi le ho tiea ha lijana li lokela ho hlahlojoa khafetsa. Lijana tsa chloroform li lokela ho qheleloa ka thoko ho asiti ea nitric le lintho tsa alkaline ho thibela karabelo.
3. Thibela pherekano: chloroform ha ea lokela ho kopanngoa le oxidant e matla, acid e matla, setsi se matla le lintho tse ling ho qoba liketso tse kotsi. Ts'ebetsong ea ho boloka, ho kenya, ho laolla le ho sebelisoa, tlhokomelo e lokela ho lefshoa ho thibela ho thulana, ho ferekana le ho sisinyeha, ho qoba ho lutla le likotsi.
4. Thibela motlakase o tsitsitseng: Nakong ea ho boloka, ho kenya, ho laolla le ho sebelisa chloroform, thibela motlakase o tsitsitseng. Mehato e nepahetseng e lokela ho nkoa, joalo ka fatše, ho roala, thepa ea antistatic, joalo-joalo.
5. Leibole ea ho tsebahatsa: Sets'oants'o sa chloroform se lokela ho tšoauoa ka lileibole tse hlakileng le boitsebahatso, ho bontša letsatsi la polokelo, lebitso, mahloriso, bongata le lintlha tse ling, e le ho nolofatsa taolo le boitsebahatso.
Lisebelisoa
Boikemisetso ba cobalt, manganese, iridium, iodine, moemeli oa ho ntša phosphorus. Boikemisetso ba phosphorus ea inorganic, khalase ea manyolo, mafura, resin ea rabara, alkaloid, boka, phosphorus, solvent ea iodine ka serum.
